This is the next total eclipse that will be visible from the USA. The animation shows the shadow of the Moon moving across the Earth during the eclipse. Within the lightly shaded area of the shadow only a partial eclipse would be seen. The fraction of the Sun covered is very small at the edge of the shadow, and increases towards the centre of the shadow area. The area of total eclipse is marked by the tiny dark area at the centre of the shadow.
This animation of a solar eclipse was produced by Andrew Sinclair. The respective animation currently appears on the author's website. (Permission to freely reproduce the eclipse animation is gratefully acknowledged).
